Answer:
6x²+40=31x
6x²-31x+40=0
6x²-15x-16x+40=0
3x(2x-5) -8(2x-5)=0
(2x-5)(3x-8)=0
X= 5/2 or 8/3

- Answer:6x^2+40=31x can also be written as by transposition;
- 6x^2-31x+40
- Factors of 240x^2 that give sum as -32x are -15x and -16x;
- thereby
- 6x^2-15x-16x+40
- 3x(2x-5)-8(2x-5)
- (2x-5)(3x-8)
- Therefore the answer is
- (2x-5)(3x-8)
- hope this helps
